...... Like an insignificant piece of kryptonite in batman beyond(The Call)... one armor like that should be stored with the best possible security in the BATCAVE.. And not give to anyone the chance to steal something belonging to Batman

He uses that armor against Darkseid is more dangerous and better than one piece of kryptonite.. and ideal for use against superman..

Maybe lost that glove is a silly form to say... you will not see that armor again

the armor was in a secret bat cave in the moon but you know comics,it dosent matter, the writer always find a way to put stuff like that back in action after all thats one of the most powefull suits batman has
